Embodiment
[disclosure problem to be solved]
Nonaqueous electrolyte battery with above-mentioned existing lead, is contained in the state of by above-mentioned lead bending mostly
Electronic instrument.Therefore, in the manufacture of above-mentioned electronic instrument, lead possessed by above-mentioned nonaqueous electrolyte battery is in lead sometimes
Conductor is bent over by the position that insulating layer coats, and is sent in the case where maintaining the bending shape to lower procedure.Therefore, contemplating
The lead of bending shape can be suitably maintained by lead bending and in the case of use, it is expected to be not susceptible to spring back.
Herein, leading-in conductor is the metals such as aluminium, is plastically deformed when having carried out bending, and generation attempts to keep bending shape
Power.On the other hand, insulating layer is resin etc., therefore the elastic deformation when having carried out bending, and generation attempts to answer from bending shape
Originally it was the power of original shape.It is in 2 power, attempt to be restored to from bending shape as caused by the elastic deformation of insulating layer
In the case that the power of shape originally more strongly acts on, above-mentioned lead, which occurs, can not keep curved shape, somewhat be restored to original
Shape phenomenon (rebound).But rebound be the material as such as made of metal leading-in conductor and resin-made insulating layer not
With 2 components interaction and the complicated phenomenon that occurs, therefore, it is difficult to predict exactly in leading-in conductor and insulating layer
Middle which kind of component of application can just be adequately suppressed rebound.
It is an object of the invention to provide carry out bending using when be not susceptible to spring back, can suitably maintain Curved
The electric component lead and electric component of shape.
[The effect of invention]
According to foregoing invention, using the teaching of the invention it is possible to provide carry out bending using when be not susceptible to spring back, can suitably maintain to bend
The electric component of the shape excellent electric component of lead and operating efficiency.
[explanations of embodiments of the present invention]
Electric component involved by one embodiment of the present invention has short strip shape conductor with lead and leads the short strip shape
A pair of of dielectric film of the two sides cladding of body, in the electric component lead, sets by the elasticity modulus of above-mentioned short strip shape conductor
For Dm [Pa], the section second moment of every 1mm width is set to Im[m4/ 1mm], and by the average elasticity mould of above-mentioned a pair of of dielectric film
Amount is set to Di[Pa], I is set to by the section second moment of every 1mm widthi[m4/ 1mm] in the case of, represented by following formulas (2)
Elastic restoring force R [the Nm of every 1mm width of dielectric film2/ 1mm] relative to the short strip shape conductor represented by following formulas (1)
Every 1mm width shape-retaining force H [Nm2/ 1mm] the ratio between (R/H) be less than or equal to 0.15,

Herein, the reason for being sprung back in lead is considered as, as described above with being become by the plasticity of short strip shape conductor
Attempt to keep the power of bending shape to compare caused by shape, attempt to be restored to from bending shape as caused by the elastic deformation of dielectric film
The power of shape originally more strongly acts on.If it is therefore contemplated that power caused by the plastic deformation as short strip shape conductor is increased, phase
Anti- power caused by the elastic deformation as dielectric film is reduced, then suppresses rebound and easily maintains the bending shape of lead.Herein,
Whether lead is able to maintain that bending shape, that is, the generation easiness sprung back, is considered depending not only upon short strip shape conductor, dielectric film
Material, also rely on their thickness, shape.Therefore, the inventors discovered that, can be by by by electric component lead
The section second moment of the elasticity modulus of short strip shape conductor and every 1mm width is set to every 1mm wide that the above-mentioned formula (1) of parameter represents
The shape-retaining force of degree, judges the influence that the short strip shape conductor of the electric component lead brings rebound.In addition, the present inventor
